秘密侦查不同于技术侦查,其含义广于后者。秘密侦查完全隐蔽化的做法是不符合世界各国的立法通例的,西方大多数国家均在其本国法律中明确规定了秘密侦查。根据我国签署或者加入的国际条约的规定,我国也应当将秘密侦查法制化。对秘密侦查的法律监督规制,根据我国的国情和特色,应当由检察官来决定比较适宜。 Secret investigation is different from technical investigation, its meaning is broader than the latter. The complete concealment of the secret investigation is not in line with the general legislation of various countries in the world. Most Western countries have clearly stipulated the secret investigation in their own laws. According to the provisions of the international treaties signed or acceded to by our country, our country should also legalize the secret investigation. The legal supervision and regulation of the secret investigation should be decided by the prosecutor according to the national conditions and characteristics of our country.
